G5, i hope you don't mind the informal address.

You are probably aware that the head loses a lot more heat in the waer than the body. So carrying simple things like a woolen hat help the thernal recovery process. a good run with a towel help get the head and other parts warm too.

It's worth sticking a warm change of clothes in your drynag as well. TPA Thermal protective aids are quite cheap and wiill do a job in an emergency.

Hand held in the water, it's better than nothing but it's range is restricted by the height you are transmitting from and power is restricted cos it runns on batteries and knocks out 6 wats max.

so in conclusion and on the basis I can't interest you in a trawler girl from Peterhead then I'd fit footstraps to your sea rider. If you've already got em I'd start using them.

Some may say that the footstrops might damage your ankle in a big bump. That might be true but ask yourself how many people die of Hypothermia and how many die of a sprained ankle.

Funny you should say that but I've been doing that tonight, the foot straps not the trawler girl.
The only time I've been "ejected" from a RIB I hurt my ankle, that was because my mate thought he could stop me by grabbing my welly!

First I'd like to echo everyone else by saying I'm glad that things worked out for you and that both you and your girlfriend are both fine.

What surprises me more however is that you don't experience this more often? You where as mad as a hatter during the Searider Cruise

However it does highlight what can happen in good conditions. I tend not to wear some of my personel safety equipement like Handheld VHF, flares, Gekkos etc untill the conditions get threatening and this just shows you what can happen unexpectantly.

Wouldn't trim tabs help with Chine walking?

Begging your pardon your chubbiness but work this out. Your body loses heat in the water a lot faster than in air. If you're bobbing about in a LJ, your head is out of the water.

So, where is most of the heat going from?

An average head represents 7-10 percent of skin area. (20 per cent in your case). Why does that 7-10 per cent lose heat faster than the other 93-90 per cent of the body?

ps. Happy Christmas

Careful you are not one of the 2

Right I am only reiterating what I was taught on my rya sea survival course and for that matter my BOSIET course

I wouldn't begin to argue with you as I have far to much respect for your anatomical and medical knowledge. and I can only handle one argument at a time.

But I have to say I am now confused.

re the warm clothes I have been chucked in on a few occasions and I definitely found it was good to change into them

Merry Christmas to you too , I s'pose

Is it not true that shock/cold draws blood to vital functions ie organs and brain. Would that not cut down heat loss from the body, but still be almost the same from the head regardless of relative area?

Thats just it Andy, i do experience it quite often but always been comfortable with it, especially in more lumpy sea conditions, but on this occassion it was relatively calm. Maybe in future i will only go out in sh*t weather conditions, beautiful winter days are far too scary for me

You should know better - instructors on these courses have no real experience/direct research they've just learned a bunch of stuff that someone on their course told them - so one piece of mis-information gets propogated down the line!

Although I suspect DM is winding you up a little because of how you phrased it! I'm surprised he didn't ask where you should 'run' to on a SR4 . On a more serious note I thought 'rubbing' a casualty with potential hypothermia was not advised (encourages peripheral blood vessels to open up - sending cold blood back to vital organs and further cooling the warmer blood by exposing to skin).

Glad you were both okay Gibbo - makes our cock up (thanks Polwart ) seem but a minor inconvienience compared to actually ending up out of the RIB - interesting though that even then you had a pre warning to not go out with a dead battery as a hurdle - is there a Saint of RIB's????

Will be looking at some personal flares - they seems a good idea

Take care Gibbo
